The utility model discloses a portable hygienic product gum peel strength detection device, which relates to the technical field of hygienic product detection, and comprises a shell, the inner wall of the shell is fixedly connected with a detection mechanism, the detection mechanism comprises a rolling barrel, and the outer surface of the rolling barrel is rotatably connected with the inner wall of the shell. The outer surface of the winding barrel is rotationally connected with a pull strap and a first gear, the inner bottom wall of the shell is fixedly connected with a servo motor, the power output end of the servo motor is fixedly connected with a second gear, and the inner wall of the shell is rotationally connected with a third gear. The outer surface of the third gear is meshed with the outer surface of the second gear, the outer surface of the second gear is meshed with the outer surface of the first gear, and a display screen is arranged on the outer side of the shell. The device can test how much the hygienic product can be pulled open by pulling force, finally detects the strength result, is small and exquisite in appearance, is convenient to carry for daily going-out test, and can improve the efficiency of test work.

The utility model discloses a shooting device and a surgical field shooting device, in the technical scheme of the shooting device, a first stator and a first rotor are parts with larger volume proportion in a first brushless motor, and the first stator and the first rotor are accommodated in a first mounting groove of the shooting device; according to the technical scheme, the first stator and the first rotor do not need to occupy the internal space of the installation holder, so that the installation of different overall volumes is reduced, the installation holder is small and exquisite, the first brushless motor can be prevented from being directly exposed, and the overall appearance structure of the shooting equipment is simpler and more compact; compared with the mode that the first stator and the first rotor are installed in the installation holder, the mode that the first stator and the first rotor are installed in the first installation groove enables the volume increase proportion of the shooting device to be small, namely the volume of the shooting device is not obviously increased, and therefore the whole appearance of the shooting device can be kept simple and small. Application and installation of the shooting equipment are facilitated.

The utility model discloses an electric steamer which comprises a base, a steamer assembly and an external water tank, the steamer assembly and the external water tank are arranged on the base, the base comprises a water storage cavity, a steam generation cavity and a heating piece arranged at the bottom of the steam generation cavity, and a separation rib is arranged between the water storage cavity and the steam generation cavity. The external water tank comprises a water supplementing cavity, a two-way water passing channel is arranged between the water storage cavity and the water supplementing cavity, and a one-way water passing channel allowing water flow to flow from the water supplementing cavity to the steam generating cavity is arranged between the water supplementing cavity and the steam generating cavity. A floater is arranged in the one-way water passing channel and floats along with the water level so as to control on-off of the one-way water passing channel. According to the electric steamer, pollutants entering the one-way water passing channel can be effectively reduced, so that the influence of the pollutants on the floating of the floater is reduced, and the service life of the floater is effectively prolonged.

The application provides a Pichia pastoris glucose oxidase production fermentation method, and belongs to the technical field of bioengineering. The fermentation method uses Pichia pastoris LY-01 gene engineering bacteria producing glucose oxidase as a starting strain, adds a fermentation medium in a fermentation tank, adds PTM1 salt after sterilization and temperature reduction, and then inoculates seed liquid for primary fermentation. When the concentration of reducing sugar in the fermentation liquid is reduced to below 0.5%, glucose solution and PTM1 salt are added for secondary fermentation. When the concentration of reducing sugar in the fermentation liquid is reduced to below 0.5% again, a mixed solution of glycerol, methanol and water and PTM1 salt are added for mixed feeding fermentation. The mixed solution of methanol and PTM1 salt is added in the fermentation liquid for induction fermentation. The enzyme activity reaches 11309 U / mL after 192 h of fermentation. In the fermentation method, the dynamic strategy of multi-stage carbon source control, especially the mixed feeding stage and the induction fermentation of methanol addition, further realizes the cell density and long-time efficient induction expression, so that high-yield glucose oxidase is obtained.

The utility model provides a portable lead seal device, include: the winding wheel of the lead seal silk is placed, the cutting device of setting in winding wheel one end, press lead seal bomb device and lead seal bomb placement box, winding wheel is wound with the lead seal silk of different material in proper order on, winding wheel center inside cavity setting, form the storage cavity, winding wheel's other end sets up a word to start. The lead seal silk of different material is wound on winding wheel, uses, draws out the lead seal silk arbitrary length, passes through the cutting device and cuts the lead seal silk, takes out the lead seal bomb in lead seal bomb placement box, after the lead seal silk string good lead seal bomb, through the hand pole and presses down, deflates the lead seal bomb, completes the lead seal operation. The utility model provides a portable lead seal device, the degree of integration is high, can effectively improve the work efficiency of lead seal operation.
